No, Steph didn't die in War Games because of Bruce, and Bruce isn't the bad guy in the story. Like, y'all are so blinded by your anger for how he treated her that you totally forget he did so to protect her because he was scared she was going to get killed. He did not push her to get killed, he was pushing her to stop, it's not his fault that these kids just don't stop. And I'm not denying he was a huge jerk to her, he was, but he is not responsible for her death when he had been telling her to stop before she got killed.
Also, it is ignoring his own behavior toward Steph during War Games. Not once do he blames her. He just wants to save her and avenge her after bringing her to Leslie. He was taking all the responsibilities for anything going south. He was ready to die with Black Mask BEFORE STEPH WAS DECLARED DEAD for what happened to Steph.
In the end, y'all are repeating what Leslie keep saying in War Games: that everything is Bruce's fault and he is to blame for everything bad. Leslie, who killed Steph to teach Bruce a lesson, which was retconned later to "simply" kidnapping an unconscious minor and moving her to another continent, away from her friends and family to who she said the girl was dead, supposedly to protect Steph from being a vigilante, by trapping Steph in a situation she has no control over. Like, Leslie is in the wrong guys, how can you not see that as Steph fans? Why do Bruce trying to stop Steph from being a vigilante by being mean is the worst thing ever, but Leslie trying to do the same thing by kidnapping the girl and taking her to Africa isn’t important?
Bruce did not kill Steph, he is not responsible for her death, and just like with Jason, saying so isn't saying she is at fault. There are actual murderers in the stories.
For y'all, Steph died because Bruce didn't want her to be a vigilante, while, in the story, she "died" by Leslie's hand to teach Bruce to stop training vigilantes. He is literally stuck in a "damn in you do, damn if you don't" situation. For this fandom, Jason died because Bruce let him be a vigilante, but Steph died because he didn't let her be one. This is stupid.
